CALIFORNIA.

CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 365,754, dated June 28,R87.

Application filed January 29, 1987. Serial No. 226,042. (No model.) I

To all whom it may concern.-

Be it known that we, BENJAMIN W. LYON and REUBEN MUNRo, citizens of theUnited States of America, and residents of the city and county of SanFrancisco, State of California, have invented new and usefulImprovements in Automatic Top-Feed Lubricators for Raih oad-Oar Axle-BoxBearings, of which the following is a full, clear, and exactdescription, referring to the accompanying drawing.

Our object, which we obtain in our car axle lubricator, is to preventthe oil from dripping on the axle when the car stands still, and to feedthe oil to the axle and bearing whenever These objects we obtain by thedevices and mechanism hereinafter described and set forth.

The figure is a vertical elevatiouof our caraxle lubricator.

Through the car-axle box and hearing A We bore a suitable hole, andprovide the same with suitable screw-th read for screwing therein theoil pipe or channel B. This pipe is threaded at both ends, and the upperend of pipe B is screwed to wooden disk D, which forms the bottom of theoil-cup, and to which the sides F are firmly screwed. Ve prefer to closeour oil-cup with a tight-fitting cover, G. The inner top edge of thepipe or channel B is beveled to a suitable angle for the purpose ofgiving a suitable closingsurface for the head of the plug or stopper 0.We prefer to make the stopper 0 of the shape as shown in the drawing;but we do not confine ourselves to that shape or form, as any othersuitable shape may effect the same result.

, To the oil-cup we properly secure asuitableadjustable gage, E, andplaced over the plug or stopper'O. This plug is stoppering up the pipeB, and prevents the oil from flowing down the pipe when the car is notin motion, while a gage is provided for the purpose to prevent the plugfrom rising too far when the carjolts, and the distance between the gageand the top of the plug is spaced or regulated by the gage. Forinstance, a large space will admit the plug to rise suliiciently whenthe ear jolts to obtain thereby a large flow of oil for the bearing andaxle, while a smaller space between the gage and the plug admits of acorresponding smaller flow ofoil.

We do not confine ourselves to the shape or form of the gage as shown inthe drawing, as

any other suitable device by which the gaging of the rise for the plugor stopper is effected will answer our purpose.

In operating our caraxle lubricator we fill the oil'cup with oil, andwhen the carjolts then the plug or stopper Ojolts and rises also,whereby an opening between the head of the plug or stopper 0 and thepipe B is made for the oil to pass through and down the pipe or channeland upon the car-axle, lubricating the same and the bearing.

We do not confine ourselves to the shape of 6 the oil-cup, as described,as any other oil cup may be changed readily to admit of the use andapplication of our stopper and gage.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is

In a car axle lubricator, the combination, with the axle-bearing A, ofthe oil-cup F, connected thereto by means of the screw-threaded pipe B,stopper or plug 0, located in the channel of said pipe, and gage E,limiting the upward movement of said stopper or plug, substantially asset forth.
